Identify the likely structure dipole moment of the theoretical molecule C(OH)3Cl.
Provide a hand-drawn illustration showing the molecule's 3D structure and dipole moment if applicable.
(a) How does a polar molecule differ from a nonpolar one? (b) Atoms X and Y have different electronegativities. Will the diatomic molecule X—Y necessarily be polar? Explain. (c) What factors affect the size of the dipole moment of a diatomic molecule?
Molecules can be polar because of the unsymmetrical distribution of electrons. The dipole moment, μ Q r
μ=Q×r
The SI unit of dipole moment is the coulomb-meter (C⋅m), but another common unit is the debye (D). The two are related as
3.336×10^−30 C⋅m=1 D
The percent ionic character is a comparison of the measured dipole moment of the bond to the expected dipole moment if electrons are instead transferred:
%ionic character=measured dipole/if electrons transferred×100%
The dipole moment if electrons are completely transferred is one for which a full unit of charge (1.60×10^−19 C) exists on each end of the bond.
The dipole measured for HI is 0.380 D. The bond distance is 161 pm. What is the percent ionic character of the HI bond?
Express your answer as a percent to three significant figures.
Describe the molecular dipole of OCl2.
